Warrants are valued using a fair value based method, whereby the fair value of the warrant is determined at the warrant issue date using a market-based option valuation model based on factors including an evaluation of the Company’s value as of the date of the issuance, consideration of the Company’s limited liquid resources and business prospects, the market price of the Company’s stock in its mostly inactive public market and the historical valuations and purchases of the Company’s warrants. When warrants are issued in combination with debt or equity securities, the warrants are valued and accounted for based on the relative fair value of the warrants in relation to the total value assigned to the debt or equity securities and warrants combined. Concentrations of credit risk: The Company's financial instruments that are exposed to concentrations of credit risk consist of cash. The Company's cash is in demand deposit accounts placed with federally insured financial institutions and selected brokerage accounts.

In some cases, the inputs used to measure an asset or liability may The fair value of cash and accounts payable approximates their carrying amounts due to their short-term maturities. The fair value of the loan payable is indeterminable at this time due to the nature of the arrangement with a state agency and the fact that it is in default.

Actual results could differ from those estimates. Recent Accounting Pronouncements: The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a study to determine the consequences of the change to its financial statements and assures that there are proper controls in place to ascertain that the Company’s financial statements properly reflect the change.
