If the asset is determined to be impaired, the impairment loss is measured based on the excess of its carrying value over its fair value. Assets to be disposed of are reported at the lower of their carrying value or net realizable value. The FASB ’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs.

Goodwill is not may not No 50 no December 31, 2016 2015, Fair Value of Financial Instruments The Company has categorized its financial assets and liabilities measured at fair value into a three ’s guidance. Fair value is defined as an exit price, the amount that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and require less judgment in measuring fair value. Conversely, financial assets and liabilities that are rarely traded or not Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period enacted.

Stock-Based Compensation The Company accounts for stock-based awards issued to employees in accordance with FASB guidance. Such awards primarily consist of options to purchase shares of common stock. The fair value of stock-based awards is determined on the grant date using a valuation model. The fair value is recognized as compensation expense, net of estimated forfeitures, on a straight line basis over the service period which is normally the vesting period. Basic and Diluted Net Loss Per Share Basic and diluted net loss per share has been calculated by dividing net loss by the weighted average number of common shares outstanding during the period. The following common stock equivalents were excluded from the computation of diluted net loss per common share because they were anti-dilutive. The exercise of these common stock equivalents would dilute earnings per shares if the Company becomes profitable in the future.

The Financial Accounting Standards Board ’s (“FASB”) guidance on goodwill and other intangible assets states that an asset with an indefinite useful life is not Long-Lived Assets Long-lived assets with definitive lives consist primarily of property and equipment, and certain intangible assets.

If the asset is determined to be impaired, the impairment loss is measured based on the excess of its carrying value over its fair value. Assets to be disposed of are reported at the lower of their carrying value or net realizable value. The FASB ’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs. This guidance requires the recognition of an asset retirement obligation and an associated asset retirement cost when there is a legal obligation associated with the retirement of tangible long-lived assets.

Goodwill is not may not No 50 no December 31, 2016 2015, Fair Value of Financial Instruments The Company has categorized its financial assets and liabilities measured at fair value into a three ’s guidance. Fair value is defined as an exit price, the amount that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and require less judgment in measuring fair value. Conversely, financial assets and liabilities that are rarely traded or not Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

Stock-Based Compensation The Company accounts for stock-based awards issued to employees in accordance with FASB guidance. Such awards primarily consist of options to purchase shares of common stock. The fair value of stock-based awards is determined on the grant date using a valuation model. The fair value is recognized as compensation expense, net of estimated forfeitures, on a straight line basis over the service period which is normally the vesting period. Basic and Diluted Net Loss Per Share Basic and diluted net loss per share has been calculated by dividing net loss by the weighted average number of common shares outstanding during the period. The following common stock equivalents were excluded from the computation of diluted net loss per common share because they were anti-dilutive. The exercise of these common stock equivalents would dilute earnings per shares if the Company becomes profitable in the future.

The criteria includes circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not not Conversion options that contain variable settlement features such as provisions to adjust the conversion price to those more favorable than that featured in the hybrid contract generally result in their bifurcation from the host instrument.

Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy [Policy Text Block]		FCC Licenses Federal Communications Commission (“FCC”) licenses are initially recorded at cost and are considered to be intangible assets with an indefinite life because the Company is able to maintain the license indefinitely as long as it complies with certain FCC requirements. The Company intends to and has demonstrated an ability to maintain compliance with such requirements. The Financial Accounting Standards Board ’s (“FASB”) guidance on goodwill and other intangible assets states that an asset with an indefinite useful life is not
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]		Long-Lived Assets Long-lived assets with definitive lives consist primarily of property and equipment, and certain intangible assets.

If the asset is determined to be impaired, the impairment loss is measured based on the excess of its carrying value over its fair value. Assets to be disposed of are reported at the lower of their carrying value or net realizable value. The FASB ’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs.

Fair Value of Financial Instruments, Policy [Policy Text Block]		Fair Value of Financial Instruments The Company has categorized its financial assets and liabilities measured at fair value into a three ’s guidance. Fair value is defined as an exit price, the amount that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and require less judgment in measuring fair value. Conversely, financial assets and liabilities that are rarely traded or not

Stock-Based Compensation The Company accounts for stock-based awards issued to employees in accordance with FASB guidance. Such awards primarily consist of options to purchase shares of common stock. The fair value of stock-based awards is determined on the grant date using a valuation model.
