2.           SHORT-TERM INVESTMENTS

All current fixed maturity securities are classified as “available for sale” and are reported at carrying value, which approximates fair value based on the discounted value of contractual cash flows. We have determined that our investment securities are available to support current operations and, accordingly, have classified such securities as current assets without regard to contractual maturities.  Investments at June 30, 2012 and December 31, 2011 consisted of certificates of deposit.  The contractual maturities of $85,533 in certificates of deposit held as of June 30, 2012 are all due within one year.
