The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. The Company’s significant accounting estimates include, but are not necessarily limited to, the allowance for doubtful accounts receivable, valuation assumptions for stock options, embedded derivatives and warrants, deferred income taxes and the related valuation allowances, accretion of discounts on debt and Series A Preferred Stock, and the evaluation and measurement of contingencies. To the extent there are material differences between the Company’s estimates and the actual results, the Company’s future consolidated results of operation may be affected.</span></div>

When it is determined that (i) an embedded feature possesses economic characteristics that are not clearly and closely related to the primary economic characteristics of the host contract, and (ii) a separate, stand-alone instrument with the same terms would meet the definition of a financial derivative instrument, then the embedded feature is bifurcated from the host contract and accounted for as a derivative instrument. The estimated fair value of the derivative feature is recorded separately from the carrying value of the host contract, with subsequent changes in the estimated fair value recorded as a non-operating gain or loss in the Company’s consolidated statements of operations.</span></div>
