NOTE 8 – ESTIMATES
The preparation of consolidated financial statements in conformity with US Generally Accepted Accounting Principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues including unbilled and deferred revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include costs and estimated earnings in excess of billings, billings in excess of costs and estimated earnings, and valuation of accounts receivable, valuation of fixed assets, valuation of inventory, valuation of deferred tax assets and the valuation of goodwill and other intangibles.
