Investments

All short-term and long-term investments are U.S. Treasury bills or U.S. Treasury notes that are classified as held-to-maturity because the Company has the positive intent and ability to hold the securities to maturity. The securities are carried at their amortized cost. The fair value of all securities is determined by quoted market prices. All long-term investments mature in less than two years. At March 31, 2012 the short-term investments had a fair value of $12,023,262 and a carrying value of $12,026,246 and the long-term investments had a fair value of $3,003,984 and a carrying value of $3,006,052.
