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 an appeal of that decision is pending in the Eleventh Circuit Court of Appeals.  A shareholder derivative action alleging similar facts was filed in the Circuit Court of Fairfax County, Virginia, which action was voluntarily dismissed by nonsuit on June 12, 2012.  The Company believes these lawsuits are without merit and will contest them vigorously. While the outcome of any legal proceeding cannot be predicted with certainty, the Company does not expect these matters will have a material effect on its financial condition or results of operations.
