Investments	4. Investments We account for and report our investments in accordance with ASC 320, “Accounting for Certain Investments in Debt and Equity Securities.” Short-term investments are marketable securities with maturities of less than one year from the balance sheet date. All of our short-term investments are under the custodianship of a major financial institution and comprised of marketable securities consisting primarily of FDIC-insured certificates of deposit. Our policy is to protect the principal value of our investment portfolio. Our marketable securities are classified as “available-for-sale” and stated at fair value, with net unrealized gains or losses recorded as a component of accumulated other comprehensive income (expense). The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity with all amortization and accretion included in interest income. Realized gains and losses on available-for-sale securities are included in other income (loss). The cost basis of securities sold is based on the specific identification method. Interest on securities classified as available-for-sale is included in interest income. Marketable securities are evaluated periodically for impairment. If it is determined that a decline of any investment is other than temporary, then the investment basis would be written down to fair value and the write-down would be included in earnings as a loss.

4. Investments

We account for and report our investments in accordance with ASC 320, “Accounting for Certain Investments in Debt and Equity Securities.” Short-term investments are marketable securities with maturities of less than one year from the balance sheet date. All of our short-term investments are under the custodianship of a major financial institution and comprised of marketable securities consisting primarily of FDIC-insured certificates of deposit. Our policy is to protect the principal value of our investment portfolio.

Our marketable securities are classified as “available-for-sale” and stated at fair value, with net unrealized gains or losses recorded as a component of accumulated other comprehensive income (expense). The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity with all amortization and accretion included in interest income. Realized gains and losses on available-for-sale securities are included in other income (loss). The cost basis of securities sold is based on the specific identification method. Interest on securities classified as available-for-sale is included in interest income. Marketable securities are evaluated periodically for impairment. If it is determined that a decline of any investment is other than temporary, then the investment basis would be written down to fair value and the write-down would be included in earnings as a loss.

At September 30, 2011, the fair value of our short-term investments was $5,522,955. The cost basis of such investments was $5,523,201 and unrealized gains were $25.
