We cannot assure you that any additional financing will be available to us on acceptable terms, or at all. The inability to raise capital would adversely affect our ability to achieve our business objectives.

From time to time, we may explore additional financing sources and means to lower our cost of capital, which could include equity, equity-linked and debt financing.

The inability to raise capital would adversely affect our ability to achieve our business objectives.
Revenue Recognition Application of the accounting principles in GAAP related to the measurement and recognition of revenue requires us to make judgments and estimates. Complex arrangements with nonstandard terms and conditions may require significant contract interpretation to determine the appropriate accounting. Specifically, the determination of whether we are a principal to a transaction or an agent can require considerable judgment.
