(11) Concentration of Credit Risk

The Company maintains its cash accounts with three commercial banks that, at times, may exceed federally insured limits. The amount on deposit at September 30, 2013 exceeded the insurance limits of the Federal Deposit Insurance Corporation by approximately $0.97 million. In addition, total cash and cash equivalents include $5.7 million held in the First American Prime Obligations Fund and $1.5 million held at UBS that are not federally insured. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents.
