[1] The Company no longer relied upon broker quotes or other models involving unobservable inputs to value these securities, as there were sufficient observable inputs (e.g., trading activity) to validate the reported fair value. As a result, the Company transferred all securities from Level 3 to Level 2 during the year ended December 31, 2011.
