Nature of Operations

1.	Nature of Operations

The company was originally incorporated in California in 1997, and reincorporated in Delaware in 2014. The company is engaged in the development and sale of wireless communications applications, including at times the sale and installation of equipment used to run these applications. The company’s applications are primarily marketed to the end users of the wireless communications carriers under licensing agreements with the company. The company also sells certain applications directly to end users. The company maintains offices in Woodland Park, New Jersey, Reston, Virginia and San Diego, California.

The company has acquired nationwide licenses to spectrum in the 900MHz band and operating equipment from Sprint Corporation pursuant to the Sprint APA (as defined below) (the “Spectrum Assets”) and is developing a dedicated dispatch network to offer push to talk (“PTT”) service in major markets throughout the United States.

On September 15, 2014, the company completed an acquisition from Sprint Corporation of (i) FCC licenses sufficient to operate a nationwide dispatch network in the 900 MHz band and (ii) certain 900 MHz equipment. The company is now focused on deploying a dedicated, wide-area, two-way radio network. Over time, the company intends to deploy the network in 20 major metropolitan areas throughout the United States, with the first markets to be located in the South and Northeast regions, with additional markets to be located in the Midwest, Southwest and West Coast regions, and to focus on serving dispatch-centric, small and medium-sized businesses. For this targeted set of customers, the company intends to offer its Dispatch Plus communication solution. Dispatch Plus will combine Motorola Solutions Inc.’s and its subsidiaries’ (collectively, “Motorola”) state-of-the-art digital radio technology with pdvConnect. Built with the commercial dispatch user in mind, the Motorola Digital Technology architecture will allow the company to provide a highly reliable, instant and wide-area PTT communication solution. Also developed for dispatch-centric businesses, pdvConnect is an easy to use and efficient workforce management solution that enables businesses to locate and communicate with field workers and improve documentation of work events and job status.

The company has historically funded operations through the issuance of debt and equity instruments. The company had access to a line of credit of up to $3.0 million with a related party (see Note 6) which it subsequently repaid and terminated in September 2014.

During the nine months ended December 31, 2014, the Company:

Entered into an Asset Purchase Agreement with certain wholly-owned subsidiaries of Sprint Corporation (the “Sprint APA”) to purchase the nationwide Spectrum Assets for a total of $100.0 million, with $90.0 million paid in cash from the proceeds of the private placement the company completed in June 2014 (the “June 2014 Private Placement”) (see below) and $10.0 million paid in 500,000 shares of common stock (at a price equal to $20.00 per share).

Completed the June 2014 Private Placement, on June 10, 2014, in which the company sold 10,925,000 shares of common stock at a purchase price of $20.00 per share. The net proceeds from the June 2014 Private Placement after deducting expenses including professional fees and the payment of initial placement fees, were approximately $202 million. Approximately 96% of the net proceeds, or approximately $196 million (net of any initial purchaser’s /placement agent’s discount and placement fees), were held in trust until the closing of the Sprint APA. In September 2014, a portion of the proceeds from the sale of common stock was used to:

•

Pay the outstanding working capital line for $1,470,000 and $351,073 in accrued interest with 65,000 shares of common stock and $521,073 in cash;

•

Pay the promissory note of $540,000 and $272,842 in accrued interest in cash;

•

Pay the outstanding Series AA convertible promissory notes owed to certain employees for $423,852 and $283,856 in accrued interest in cash;

•

Pay $367,695 owed to certain employees for deferred compensation in cash; and

•

Convert the Redeemable Notes (as defined in Note 6 below) of $1,016,956 into 77,734 shares of common stock based on 140% of the outstanding principal and accrued interest.

Closed agreements with Motorola on September 15, 2014, under which Motorola invested $10.0 million to purchase 500,000 Class B Units of the company’s subsidiary, PDV Spectrum Holding Company, LLC (at a price equal to $20.00 per unit) and leased some of the Spectrum Assets for a prepaid price of $7.5 million.

Issued 1,146,457 stock options to purchase the company’s common stock and 83,804 restricted units of the company’s common stock.

In connection with the June 2014 Private Placement, the company completed a number of actions, including:

•

The reincorporation of the company from California to Delaware;

•

The conversion of all outstanding shares of the company’s Series AA Preferred Stock into 748,722 shares of the company’s common stock, the exchange of 661,581 outstanding warrants to purchase shares of Series AA Preferred Stock into 29,809 shares of common stock, and the conversion of the remaining options and warrants to purchase shares of the company’s Series AA Preferred Stock into options or warrants to purchase shares of common stock and the conversion of restricted stock units for shares of its Series AA Preferred Stock into restricted stock units for shares of common stock;

•

The amendment of outstanding Redeemable Notes, in the aggregate principal of $1,016,956, to provide that the Redeemable Notes would automatically be converted at the closing of the Sprint APA into that number of shares of common stock equal to the sum of 140% of the principal plus the outstanding interest on such Redeemable Notes through the conversion divided by $20.00 per share;

•

A 33.11451201-for-1 reverse stock split of all outstanding common stock, which was effected immediately prior to the completion of the June 2014 Private Placement. All share and per share data reported and disclosed in the accompanying financial statements have been retroactively adjusted to give effect to the reverse stock split.

•

Entered into an agreement with Motorola on May 12, 2014, under which Motorola agreed to provide the company with their digital radio technology and handsets that it intends to deploy as part of the nationwide network.

•

An increase in the authorized shares of common stock to 100,000,000 shares and preferred stock to 10,000,000 shares, and a change in the par value of the company’s common stock from no par value to $0.0001 per share. The preferred stock has first priority on liquidation preference over the common stock.

Summary of Significant Accounting Policies

2.	Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The accompanying interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), which 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 and expenses during the reporting period. Accordingly actual results could differ from those estimates.

The accompanying financial statements as of December 31, 2014 and for the three and nine month periods ended December 31, 2014 and 2013 are unaudited. These unaudited financial statements have been prepared in accordance with US GAAP for interim financial information and are presented in accordance with the requirements of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by US GAAP for complete financial statements.

In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended December 31, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2015. The unaudited financial statements should be read in conjunction with the audited financial statements as of and for the year ended March 31, 2014 and footnotes thereto included in the company’s final prospectus dated and filed with the SEC on January 26, 2015, as supplemented by the prospectus supplement filed February 2, 2015 with the SEC.

The balance sheet as of March 31, 2014 contained herein has been derived from the audited financial statements as of March 31, 2014 and the stockholders’ (deficiency) equity section has been retroactively restated for the stock split discussed in Note 1.

Furniture, Fixture and Equipment

Furniture, fixture and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.

The carrying amount at the balance sheet date of long-lived assets under construction include construction costs to date on capital projects that have not been completed and assets being constructed that are not ready to be placed into service. These costs will be transferred to furniture, fixture and equipment when substantially all of the activities necessary to prepare the assets for their intended use are completed. Depreciation commences upon capitalization.

Intangible Assets

Intangible assets are wireless licenses that will be used to provide the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the Federal Communications Commission (FCC). License renewals have occurred routinely and at nominal cost. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the company’s wireless licenses. As a result, the wireless licenses are treated as an indefinite-lived intangible asset and the company will evaluate the useful life determination for wireless licenses each year to determine whether events and circumstances continue to support an indefinite useful life.

Patent Costs

Costs to acquire a patent on certain aspects of the company’s technology have been capitalized. These amounts are amortized, subject to periodic evaluation for impairment, over statutory lives following award of the patent. Accumulated amortization amounted to $335,435 at December 31, 2014 and $303,305 at March 31, 2014, respectively. Amortization expense was $10,710 and $11,250 for the three months ended December 31, 2014 and 2013, respectively. For the nine months ended December 31, 2014 and 2013, amortization expense was $32,130 and $33,750, respectively. The amortization expense is estimated to aggregate $40,000 per year over the next five year period.

Allowance for Uncollectible Receivables

An allowance for uncollectible receivables is estimated based on a combination of write-off history, aging analysis and any specific known troubled accounts. At December 31, 2014 and March 31, 2014, management provided an allowance of $37,248 and $12,619, respectively, for certain slow paying accounts.

Revenue Recognition

The company recognizes revenue in the period in which the services are provided and when collectability of the revenue is reasonably assured. In accordance with the guidance provided in Accounting Standards Codification (“ASC”) Topic 605-45-45, Revenue Recognition – Principal Agent Considerations, the company has determined that it is the primary obligor with respect to the service revenue derived from sales of the company’s software applications through its domestic carrier partners. As a result, revenue is recorded at the gross amount billed to end-user customers for sales to the domestic carrier partners. The company recognizes revenue for its international carrier on the net amount billed since it has determined that it is not the primary obligor. The company also sells certain applications directly to end-users through its direct sales force, which are billed and collected directly by the company.

In September 2014, Motorola made an upfront, fully-paid leasing fee of $7.5 million in order to lease a portion of the FCC licenses. The payment of the fee was accounted for as Deferred Revenue as of September 30, 2014. The company recognizes leasing revenue in accordance with ASC Topic 840, Leases. The fee is amortized using the straight-line method over the lease term of approximately ten years which represents the time frame in which the benefits of the leased property are expected to be depleted.

Cost of Revenue

The company’s cost of revenue includes the portion of service revenue retained by its domestic carrier partners pursuant to its agreements with these parties, which may include network services, connectivity, SMS service and special equipment expenses, sales, marketing, billing and other ancillary services. The company also includes the costs associated with the operation of its cloud-based solutions and dispatch network.

Product Development Costs

The company charges all product and development costs to expense as incurred. Types of expense incurred in product and development include employee compensation, consulting, travel, facility costs and equipment and technology costs.

Stock Compensation

The company accounts for stock options in accordance with US GAAP, which requires the measurement and recognition of compensation expense, based on the estimated fair value of awards granted to employees and directors. The company estimates the fair value of share-based awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the company’s statements of operations over the requisite service periods.

To calculate option-based compensation, the company uses the Black-Scholes option-pricing model. The company’s determination of fair value of option-based awards on the date of grant using Black-Scholes model is affected by assumptions regarding a number of subjective variables.

No tax benefits were attributed to the share-based compensation expense because a full valuation allowance was maintained for all net deferred tax assets.

Income Taxes

The company follows the liability method of accounting for income taxes. Under this method, taxes consist of taxes currently payable plus those deferred due to temporary differences between the financial statement carrying amounts and the tax bases of certain assets and liabilities using tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.

Accounting for Uncertainty in Income Taxes

The company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the company had no uncertain tax positions that would require financial statement recognition or disclosure. The company is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2012.

Long-Lived Asset Impairment

The company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value.

Fair Value of Financial Instruments

Financial instruments, including cash, accounts receivable, accounts payable, accrued expenses and notes payable – affiliated entities are carried at cost, which management believes approximates fair value because of the short term maturity of these instruments.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09 Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This guidance is effective for interim and annual periods beginning on or after December 15, 2016. The company is currently evaluating the impact of the adoption of this accounting standard update on its financial statements.

Net Loss Per Share of Common Stock

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated entities, stock options and warrants are considered to be potentially dilutive securities. Because the company has reported a net loss for the three and nine months ended December 31, 2014 and 2013, diluted net loss per common share is the same as basic net loss per common share for those periods.

Common stock equivalents resulting from potentially dilutive securities approximated 1,800,000 and 210,000 at December 31, 2014 and 2013, respectively, and have not been included in the dilutive weighted average shares outstanding, as their effects are anti-dilutive.

Subsequent Events Evaluation by Management

Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that the financial statements were issued.

Stock Purchases Rights, Stock Options and Warrants

8.	Stock Purchases Rights, Stock Options and Warrants

The company established the Pacific DataVision 2014 Stock Plan (the “2014 Stock Plan”) to attract, retain and reward individuals who contribute to the growth and profitability of the company. This Stock Plan superseded previous stock plans although under such previous plans, 74,134 stock options were vested and outstanding as of December 31, 2014.

The company’s Board of Directors authorized and reserved 1,200,000 shares of common stock for issuance under its 2014 Stock Plan. The number of shares reserved for issuance under the 2014 Stock Plan automatically increased on January 1, 2015 and will continue to automatically increase each subsequent anniversary through January 1, 2024 by an amount equal to the smaller of 5% of the number of shares of common stock issued and outstanding on the immediately preceding December 31 or a lesser amount determined by the Board of Directors. On January 1, 2015, 623,651 shares of common stock were added to the 2014 Stock Plan and are available for future issuance.

From May 14, 2014 through December 31, 2014, the company awarded certain employees and contractors of the company 1,146,457 options to purchase shares of common stock with an exercise price of $20.00 per share. The shares have a ten year contractual life and 25% will vest on the first anniversary of grant, and the remainder will vest in three equal annual installments. Shares granted to employees are subject to vesting, future settlement conditions and other such terms as determined by the Board of Directors.

In connection with the June 2014 Private Placement, the company converted all outstanding shares of the company’s Series AA Preferred Stock into 748,722 shares of its common stock, exchanged 661,581 outstanding warrants to purchase shares of Series AA Preferred Stock into 29,809 shares of common stock, and converted the remaining options and warrants to purchase shares of the Series AA Preferred Stock into options or warrants to purchase shares of the common stock, and converted restricted stock units for shares of the company’s Series AA Preferred Stock into restricted stock units for shares of common stock.

Restricted Stock Units

Under the 2010 Stock Plan, the company issued 82,054 restricted stock units and under the 2014 Stock Plan, the company issued 1,750 restricted stock units, for shares of the company’s common stock, during the nine months ended December 31, 2014, to certain employees and contractors of the company. The company recognizes compensation expense for restricted stock units over the explicit vesting period. Vested restricted stock units are settled and issuable upon the earlier of the date the employee ceases to be an employee of the company or a date certain in the future. Stock compensation expense related to the 83,804 shares issued in the nine months ended December 31, 2014 was $1,676,080. At December 31, 2014, 128,001 restricted stock units were vested.

The Black-Scholes option model requires weighted average assumptions to be used for calculation of the company’s stock compensation expense. The assumptions used during the three and nine months ended December 31, 2014 were: the expected life of the awards was 5 years, the risk-free interest rate was 1.66%, the expected volatility was 47.0%, and the expected dividend yield was 0.0%. There was no forfeiture rate used for the calculation.

Stock compensation expense of $1,404,202 and $4,680,802 for the three and nine months ended December 31, 2014, respectively ($19,764 and $59,292 for the three and nine months ended December 31, 2013, respectively) represents $1,676,080 in expense related to the restricted stock units issued in the nine months ended December 31, 2014 and, the amortization of the fair value of options issued since fiscal year 2009. Stock compensation expense is included as part of general and administrative expense in the accompanying statement of operations. As of December 31, 2014, there was approximately $6.8 million of unrecognized compensation cost related to non-vested share options granted under the company’s stock option plans. The cost is expected to be recognized over a weighted-average period of 3.4 years. The intrinsic value of the options outstanding and exercisable at December 31, 2014 was approximately $330,000 and $305,000, respectively.

Motorola Investment

On September 15, 2014, Motorola invested $10.0 million to purchase 500,000 Class B Units of the company’s subsidiary, PDV Spectrum Holding Company, LLC (at a price equal to $20.00 per unit). The company owns 100% of the Class A Units in this subsidiary. Motorola has the right at any time to convert its 500,000 Class B Units into 500,000 shares of the company’s common stock. The company also has the right to force Motorola’s conversion into shares of its common stock on the occurrence of certain corporate events or at its election after September 15, 2016. Motorola is not entitled to any assets, profits or distributions from the operations of the subsidiary. In addition, Motorola’s conversion ratio from Class B Units to shares of the Company’s common stock is fixed on a one-for-one basis, and is not dependent on the performance or valuation of either the company or the subsidiary. The Class B Units have no redemption or call provisions and can only be converted into shares of the company’s common stock. Management has determined that this investment does not meet the criteria for temporary equity or non-controlling interest due to the limited rights that Motorola has as a holder of Class B Units, and accordingly has presented this investment as part of its permanent equity within Additional Paid-in Capital in the accompanying financial statements.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation and Use of Estimates	*Basis of Presentation and Use of Estimates* The accompanying interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), which 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 and expenses during the reporting period. Accordingly actual results could differ from those estimates. The accompanying financial statements as of December 31, 2014 and for the three and nine month periods ended December 31, 2014 and 2013 are unaudited. These unaudited financial statements have been prepared in accordance with US GAAP for interim financial information and are presented in accordance with the requirements of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by US GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended December 31, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2015. The unaudited financial statements should be read in conjunction with the audited financial statements as of and for the year ended March 31, 2014 and footnotes thereto included in the company’s final prospectus dated and filed with the SEC on January 26, 2015, as supplemented by the prospectus supplement filed February 2, 2015 with the SEC. The balance sheet as of March 31, 2014 contained herein has been derived from the audited financial statements as of March 31, 2014 and the stockholders’ (deficiency) equity section has been retroactively restated for the stock split discussed in Note 1.
Furniture, Fixture and Equipment	*Furniture, Fixture and Equipment* Furniture, fixture and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The carrying amount at the balance sheet date of long-lived assets under construction include construction costs to date on capital projects that have not been completed and assets being constructed that are not ready to be placed into service. These costs will be transferred to furniture, fixture and equipment when substantially all of the activities necessary to prepare the assets for their intended use are completed. Depreciation commences upon capitalization.
Intangible Assets	*Intangible Assets* Intangible assets are wireless licenses that will be used to provide the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the Federal Communications Commission (FCC). License renewals have occurred routinely and at nominal cost. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the company’s wireless licenses. As a result, the wireless licenses are treated as an indefinite-lived intangible asset and the company will evaluate the useful life determination for wireless licenses each year to determine whether events and circumstances continue to support an indefinite useful life.
Patent Costs	*Patent Costs* Costs to acquire a patent on certain aspects of the company’s technology have been capitalized. These amounts are amortized, subject to periodic evaluation for impairment, over statutory lives following award of the patent. Accumulated amortization amounted to $335,435 at December 31, 2014 and $303,305 at March 31, 2014, respectively. Amortization expense was $10,710 and $11,250 for the three months ended December 31, 2014 and 2013, respectively. For the nine months ended December 31, 2014 and 2013, amortization expense was $32,130 and $33,750, respectively. The amortization expense is estimated to aggregate $40,000 per year over the next five year period.
Allowance for Uncollectible Receivables	*Allowance for Uncollectible Receivables* An allowance for uncollectible receivables is estimated based on a combination of write-off history, aging analysis and any specific known troubled accounts. At December 31, 2014 and March 31, 2014, management provided an allowance of $37,248 and $12,619, respectively, for certain slow paying accounts.
Revenue Recognition	*Revenue Recognition* The company recognizes revenue in the period in which the services are provided and when collectability of the revenue is reasonably assured. In accordance with the guidance provided in Accounting Standards Codification (“ASC”) Topic 605-45-45, Revenue Recognition – Principal Agent Considerations, the company has determined that it is the primary obligor with respect to the service revenue derived from sales of the company’s software applications through its domestic carrier partners. As a result, revenue is recorded at the gross amount billed to end-user customers for sales to the domestic carrier partners. The company recognizes revenue for its international carrier on the net amount billed since it has determined that it is not the primary obligor. The company also sells certain applications directly to end-users through its direct sales force, which are billed and collected directly by the company. In September 2014, Motorola made an upfront, fully-paid leasing fee of $7.5 million in order to lease a portion of the FCC licenses. The payment of the fee was accounted for as Deferred Revenue as of September 30, 2014. The company recognizes leasing revenue in accordance with ASC Topic 840, Leases. The fee is amortized using the straight-line method over the lease term of approximately ten years which represents the time frame in which the benefits of the leased property are expected to be depleted.
Cost of Revenue	*Cost of Revenue* The company’s cost of revenue includes the portion of service revenue retained by its domestic carrier partners pursuant to its agreements with these parties, which may include network services, connectivity, SMS service and special equipment expenses, sales, marketing, billing and other ancillary services. The company also includes the costs associated with the operation of its cloud-based solutions and dispatch network.
Product Development Costs	*Product Development Costs* The company charges all product and development costs to expense as incurred. Types of expense incurred in product and development include employee compensation, consulting, travel, facility costs and equipment and technology costs.
Stock Compensation	*Stock Compensation* The company accounts for stock options in accordance with US GAAP, which requires the measurement and recognition of compensation expense, based on the estimated fair value of awards granted to employees and directors. The company estimates the fair value of share-based awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the company’s statements of operations over the requisite service periods. To calculate option-based compensation, the company uses the Black-Scholes option-pricing model. The company’s determination of fair value of option-based awards on the date of grant using Black-Scholes model is affected by assumptions regarding a number of subjective variables. No tax benefits were attributed to the share-based compensation expense because a full valuation allowance was maintained for all net deferred tax assets.
Income Taxes	*Income Taxes* The company follows the liability method of accounting for income taxes. Under this method, taxes consist of taxes currently payable plus those deferred due to temporary differences between the financial statement carrying amounts and the tax bases of certain assets and liabilities using tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.
Accounting for Uncertainty in Income Taxes	*Accounting for Uncertainty in Income Taxes* The company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the company had no uncertain tax positions that would require financial statement recognition or disclosure. The company is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2012.
Long-Lived Asset Impairment	*Long-Lived Asset Impairment* The company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value.
Fair Value of Financial Instruments	*Fair Value of Financial Instruments* Financial instruments, including cash, accounts receivable, accounts payable, accrued expenses and notes payable – affiliated entities are carried at cost, which management believes approximates fair value because of the short term maturity of these instruments.
Recently Issued Accounting Pronouncements	*Recently Issued Accounting Pronouncements* In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09 Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This guidance is effective for interim and annual periods beginning on or after December 15, 2016. The company is currently evaluating the impact of the adoption of this accounting standard update on its financial statements.
Net Loss Per Share of Common Stock	*Net Loss Per Share of Common Stock* Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated entities, stock options and warrants are considered to be potentially dilutive securities. Because the company has reported a net loss for the three and nine months ended December 31, 2014 and 2013, diluted net loss per common share is the same as basic net loss per common share for those periods. Common stock equivalents resulting from potentially dilutive securities approximated 1,800,000 and 210,000 at December 31, 2014 and 2013, respectively, and have not been included in the dilutive weighted average shares outstanding, as their effects are anti-dilutive.
Subsequent Events Evaluation by Management	*Subsequent Events Evaluation by Management* Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that the financial statements were issued.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
