The Company follows the provisions of ASC 820, “Fair Value Measurements and Disclosures” for its financial assets and liabilities, and to its non-financial assets and liabilities. ASC 820 provides a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases, require estimates of fair-market value. This standard also expanded financial statement disclosure requirements about a company’s use of fair-value measurements, including the effect of such measure on earnings. The cost of securities sold is based on the specific identification method.

The Company’s investment securities are classified as available for sale and are stated at fair value based on quoted market prices. Assets or liabilities that have recurring measurements are shown below as of March 31, 2013, and December 31, 2012:

The Company determines the fair value of its U.S. Treasury Notes, Government Securities and Corporate Bonds by utilizing monthly valuation statements that are provided by its broker. The broker determines the investment valuation by utilizing the bid price in the market. The Company also refers to third party sources to validate valuations.

ASC 320, “Accounting for Certain Investments in Debt and Equity Securities”, as amended and interpreted, provides guidance on determining when an investment is other than temporarily impaired. The Company reviews its fixed income and equity investment portfolio for any unrealized losses that would be deemed other-than-temporary and require the recognition of an impairment loss in income. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and the Company’s intent and ability to hold the investments. Management also considers the type of security, related-industry and sector performance, as well as published investment ratings and analyst reports, to evaluate its portfolio. Once a decline in fair value is determined to be other than temporary, an impairment charge is recorded and a new cost basis in the investment is established. If market, industry, and/or investee conditions deteriorate, the Company may incur future impairments. No equity investment losses were considered to be other than temporary at March 31, 2013.

Fixed income securities as of March 31, 2013, have contractual maturities as follows:

Due within one year	$	75,497,408
Due between one and five years	7,302,340
Total	$	82,799,748
