Use of Estimates [Text Block]

4.

Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Future events and their effects cannot be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences

may

be material to our consolidated financial statements. Significant estimates include assumptions about percentage-of-completion, collection of accounts receivable, the valuation, and recognition of stock-based compensation expense, valuation for deferred tax assets and useful life of fixed assets.
