Intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results could differ from the estimates and assumptions used. Property and Equipment Property and equipment is recorded at cost. Depreciation is recorded over the estimated useful lives using the straight-line method. Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized. Intangibles Intangible assets consist of purchased patents and capitalized website costs. Intangible assets are recorded at the fair value as of the date of acquisition, and intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. Goodwill The Company evaluates the carrying value of goodwill on an annual basis and between annual evaluations if events occur or circumstances change that would more likely than not first not Impairment of Long-Lived Assets Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not first not third Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair value of each class of financial instrument held by the Company: Current assets and current liabilities Notes payable Basic and Diluted Loss Per Common Share Basic loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock.

The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company’s tax benefits are fully offset by a valuation allowance due to the uncertainty that the deferred tax assets would be realized.
