Share-based Compensation	Share-based Compensation Share-based payments are measured at their estimated fair value on the date of grant. Share-based awards to non-employees are re-measured at fair value each financial reporting date until performance is completed. Share-based compensation expense recognized during a period is based on the estimated number of awards that are ultimately expected to vest. For warrants that do not vest immediately but which contain only a service vesting feature, we recognize compensation cost on the unvested warrants on a straight-line basis over the remaining vesting period. The Company uses the Black-Scholes option-pricing model to estimate the fair value of warrants and the market price of our common stock on the date of grant for the fair value. Our determination of fair value of share-based awards is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and certain other market variables such as the risk-free interest rate.
