DESCRIPTION OF BUSINESS

Organization and Description of Business

Retrophin, Inc. (the “Company”) was incorporated as Desert Gateway, Inc. (“Desert Gateway”) in the State of Oklahoma on February 8, 2008. Desert Gateway was originally a wholly-owned subsidiary of American Merchant Data Services, Inc. (“American Merchant”). In a 2008 reorganization of American Merchant, each share of outstanding common stock of American Merchant was converted into one share of Desert Gateway, while all of American Merchant’s operating assets, liabilities and tax attributes (including accumulated losses and net operating losses) carried forward to another subsidiary of American Merchant in a downstream merger with such other subsidiary. Accordingly, American Merchant is not considered a predecessor company of the Desert Gateway for accounting or legal purposes. Following the 2008 reorganization, Desert Gateway re-domiciled to Delaware. Since inception and until Desert Gateway’s merger with Retrophin, Inc., a private company (“Former Retrophin”) in December 2012 (as described below), Desert Gateway had no existing operations, and its sole purpose was to locate and consummate a merger or acquisition with a private entity.

Former Retrophin, Inc. was originally organized as a Delaware limited liability company, named Retrophin, LLC, on March 11, 2011 (“Inception”). On September 20, 2012, Retrophin filed a Certificate of Conversion to change its legal form of organization from a limited liability company to a corporation in the State of Delaware. This conversion (as more fully described in Note 8) into a corporation, which preceded the Merger on December 12, 2012, resulted in no change of ownership and was therefore considered a recapitalization of the LLC’s equity.

On September 13, 2012, Former Retrophin formed a new entity, Retrophin Pharmaceutical, Inc., a Delaware corporation and a wholly-owned subsidiary of Retrophin, Inc.

On December 12, 2012, Desert Gateway completed the transactions contemplated under the Agreement and Plan of Merger, dated as of December 12, 2012 (the “Merger Agreement”), by and among Desert Gateway, Desert Gateway Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of Desert Gateway, and Former Retrophin, our predecessor, in which Former Retrophin became a wholly-owned subsidiary and the principal operating subsidiary of the Company. The transactions contemplated by the Merger Agreement are collectively referred to herein as the “2012 Merger”. The Merger became effective on December 12, 2012, upon the filing of a certificate of merger with the Secretary of State of the State of Delaware. Accordingly, the Merger resulted in a change in control of Desert Gateway. Desert Gateway’s net assets amounted to $1,401 at the time of the merger, including $3,721 of cash and $2,320 of trade liabilities. The merger is being accounted for as a reverse merger and recapitalization of Former Retrophin into Desert Gateway, whereby Desert Gateway is the legal acquirer and Former Retrophin is the legal acquiree and the accounting acquirer in this transaction.

Upon the consummation of the Merger all of the issued and outstanding Class A Preferred shares of Former Retrophin were exchanged into the Company’s common shares at the rate of 1 to 7 (each Class A Preferred stockholder received 7 shares of the Company’s common stock) and all of the issued and outstanding share of common stock of Former Retrophin were exchanged for shares of the Company’s common stock on exchange ratio of 1 to 5 (each Common stockholder of Former Retrophin received 5 shares of the Company’s common stock).

The consolidated financial statements give retroactive effect to these changes as if the merger occurred at the inception of the Company.

On February 14, 2013, the Company changed its name to “Retrophin, Inc.” through a short-form merger pursuant to Section 253 of the Delaware General Corporation Law, with its then wholly owned subsidiary, and our predecessor, Retrophin, with the Company continuing as the surviving corporation following the merger.

On April 1, 2013, the Company changed its fiscal year end from the last day of February to a fiscal year end of December 31 in order to confirm its reporting cycle to that of Former Retrophin.

Retrophin, is an emerging biotechnology company dedicated to developing drugs for rare and life-threatening diseases. Retrophin’s primary business objective is to develop and commercialize therapies for orphan diseases, such as Duchenne muscular dystrophy, or DMD. The Company is considered to be a development stage company and, as such, the Company’s financial statements are prepared in accordance with the Accounting Standards Codification (“ASC”) 915 “Development Stage Entities.” The Company is subject to all of the risks and uncertainties associated with development stage companies.

2. LIQUIDITY AND FINANCIAL CONDITION AND MANAGEMENT’S PLANS

12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]

2. LIQUIDITY AND FINANCIAL CONDITION AND MANAGEMENT’S PLANS

The Company incurred a net loss of approximately $33.6 million, including stock-based compensation charge of $24,389,521 for the period from March 11, 2011 (inception) to December 31, 2012. At December 31, 2012, the Company had a cash balance of approximately $11,000 and a working capital deficiency of approximately $5,766,000. The Company’s accumulated deficit amounted to approximately $33,600,000 at December 31, 2012.

The Company has principally financed its operations from inception using proceeds from sales of its equity securities in a series of private placement transactions (see Note 7). The Company to date has no revenues, significantly limited capital resources and is subject to all of the risks and uncertainties that are typical of a development stage enterprise. Significant uncertainties include, among others, whether it will be able to raise the capital it needs to finance the start of its planned operations and whether such operations, if launched, will enable the Company to become a profitable enterprise.

On February 14, 2013, in connection with the closing of a private placement, we issued and sold an aggregate of 3,045,929 shares of common stock, for an aggregate purchase price of $9,137,787 in cash, and warrants to purchase up to an aggregate of 1,522,969 shares of common stock. The Company concurrently entered into a registration payment arrangement requiring it to file a Form S-1 with the Securities and Exchange Commission within 30 days of the closing date of this transaction and cause it to be declared effective by no later than 90 days of the closing date of this transaction. The registration payment arrangement provided for the Company to pay liquidated damages in the amount of 2% of the proceeds received in this transaction per month for each month that the Company is not in compliance with this requirement, not to exceed 10% in the aggregate. The Company determined that it was probable that it would not be in a position to comply with these requirements and therefore allocated approximately $360,000 of the proceeds received in this transaction to a registration payment obligation.

In the second quarter of 2013, the Company, its Chief Executive Officer and a related party became party to a series of agreements to settle up to $2,286,511 of liabilities, which Company management believes are the primary obligation of the related party. The Company and the related party have entered into indemnification agreements whereby the related party has agreed to defend and hold the Company harmless against all such obligations and amounts, whether paid or unpaid, arising from these agreements. The Company paid $593,111 of the total settlement liabilities in the second quarter of 2013 and had $1,691,400 in outstanding settlement liabilities, $300,000 of which is past due, $713,900 of which was due in July 2013, and $677,500 of which was due in August 2013. The counter parties to these agreements reserve the right to demand payment at any time. The Chief Executive Officer also agreed to deliver or cause to be delivered 47,128 shares of common stock in the Company to one of the counter parties as a separate component of one of these agreements. Accordingly, the Company does not believe it is required to record a liability for the shared-based component of this specific agreement during the second quarter ended June 30, 2013.

There is uncertainty as to whether the related party will have sufficient liquidity to repay the Company or fund the indemnification agreements should it become necessary.

Concurrent with the execution of such settlement agreements, the Company received promissory notes from the related party whereby the related party agreed to pay the Company the principal amount of $593,111 plus interest at an annualized rate of 5% as reimbursement of the payments that the Company made to settle a portion of the agreements.

These conditions raise substantial doubt about the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments relating to the recovery of assets or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Management believes the Company’s ability to continue its operations depends on its ability to raise capital. The Company entered into a licensing agreement providing it with the use of certain technology. The Company is currently developing pre-clinical and clinical studies of drug candidates. The licensing agreement described in Note 4 also enables the Company to sell the licensed technology as a research product or sublicense the technology to other third parties as alternative sources of revenue to its own product development efforts. The Company’s future depends on the costs, timing, and outcome of regulatory reviews of its product candidates and the costs of commercialization activities, including product marketing, sales and distribution. During the first quarter of 2013, the Company has raised approximately $9.95 million in certain private placement transactions. The Company expects to continue to finance its cash needs through additional private equity offerings and debt financings, corporate collaboration and licensing arrangements and grants from patient advocacy groups, foundations and government agencies. Although management believes that the Company has access to capital resources, there are no commitments for financing in place at this time, nor can management provide any assurance that such financing will be available on commercially acceptable terms, if at all.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

12 Months Ended

Dec. 31, 2012

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements follows:

Principles of Consolidation

The consolidated financial statements represent the consolidation of the accounts of the Company and its subsidiary in conformity with U.S. GAAP. All intercompany accounts and transactions have been eliminated in consolidation.

Restatement of Previously Issued Financial Statements for Additional Disclosures

The Company, while undergoing a review of its condensed consolidated financial statements for the three and six months periods ended June 30, 2013, commenced an evaluation of its accounting for a series of settlement agreements that the Company, along with certain of its related parties, entered into between April 2013 and June 2013. These agreements, which Company management originally deemed to be the primary obligation of a related party, are more fully described in Notes 2 and 12. On September 13, 2013, Company management, under the authority of the board of directors, determined that these agreements should have been disclosed in the footnotes to its consolidated financial statements for the year ended December 31, 2012. Accordingly, the Company has restated these consolidated financial statements to include these disclosures.

The Company also determined that its obligation to pay liquidated damages under a registration payment that it entered into in connection with a financing transaction it completed on February 14, 2013, which required the Company to cause a registration statement to be declared effective by the Securities and Exchange Commission by May 15, 2013, should have also been disclosed. Accordingly, the Company is restating these condensed consolidated financial statements to disclose that it allocated approximately $360,000 of the proceeds received in this financing transaction to a registration payment obligation that was deemed probable at the date that the financing transaction was completed.

Cash and Cash Equivalents

For purposes of the statement of cash flows, the Company considers cash instruments with maturities of less than three months when purchased to be cash equivalents. There are no cash equivalents as of the balance sheet date.

Property and Equipment

Property and equipment are stated at cost. Depreciation is provided for using the straight-line method over the estimated useful lives of the assets. At December 31, 2012 and 2011, property and equipment consisted of computers with an estimated useful life of three years and leasehold improvements with an estimated life of four years.

Employee Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718 Compensation — Stock Compensation (“ASC 718”). ASC 718 addresses all forms of share-based payment (“SBP”) awards including shares issued under employee stock purchase plans and stock incentive shares. Under ASC 718 awards result in a cost that is measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest and will result in a charge to operations.

Non-Employee Stock-Based Compensation

The Company accounts for equity instruments issued to non-employees in accordance with the provisions of ASC 505, Share Based Payments to Non-Employees, and ASC 718 which requires that such equity instruments are recorded at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. Non-employee stock-based compensation charges are being amortized over their respective contractual vesting periods.

Income Taxes

The Company accounts for income taxes under ASC 740 Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s unaudited financial statements. Since the Company was incorporated on March 11, 2011, all of its years of operations will be subject to examination. The Company believes that its income tax positions and deductions would be sustained on audit and does not anticipate any adjustments that would result in a material changes to its consolidated financial position.

The Company’s policy for recording interest and penalties associated with audits is to record such expense as a component of income tax expense. There were no amounts accrued for penalties or interest as of or during the period from March 11, 2011 (inception) through December 31, 2012. Management is currently unaware of any issues under review that could result in significant payments, accruals or material deviations from its position.

Prior to conversion into a corporation on September 20, 2012, as a limited liability company, the Company was treated as a partnership for Federal and state income tax purposes. Accordingly, no provision has been made for Federal and state income taxes in the accompanying financial statements for any periods preceding September 20, 2012, since all items of income or loss are required to be reported on the income tax returns of the members, who are responsible for any taxes thereon. Profits and losses are allocated based upon capital in accordance with the permissible methods under Internal Revenue Code Section 706. Further, the Company incurred losses since inception through September 20, 2012, that would have resulted in the recognition of deferred tax assets that would have been fully reserved had the Company been subject to income taxes.

The Company is subject to the New York City Unincorporated Business Tax through September 19, 2012. Subsequent to Company’s conversion to a corporation from a limited liability company on September 20, 2012, the Company will report and pay taxes based on its income or loss.

Use of Estimates

In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management is required 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, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. These estimates and assumptions include valuing equity securities in share-based payments, estimating the useful lives of depreciable and amortizable assets and estimating the fair value of long-lived assets to assets whether impairment charges may apply.

Foreign Currency Translation and Remeasurement

Under ASC 830 Foreign Currency Matters, functional currency assets and liabilities are translated into the reporting currency, US Dollars, using period end rates of exchange and the related translation adjustments are recorded as a separate component of accumulated other comprehensive income. Functional statements of operations amounts expressed in functional currencies are translated using average exchange rates for the respective periods. Remeasurement adjustments and gains or losses resulting from foreign currency transactions are recorded as foreign exchange gains or losses in the consolidated statements of operations.

Research and Development Costs:

Research and development costs are charged to operations as incurred and consist primarily of consulting services. For the year ended December 31, 2012, for the period from March 11, 2011 (inception) through December 31, 2011 and for the period from March 11, 2011 (inception) through December 31, 2012, the Company incurred approximately $524,000, $353,000, and $877,000, respectively, relating to research and development costs that are included in professional fees in the accompanying consolidated statements of operations.

Patents

The Company capitalized external cost, such as filing fees and associated attorney fees, incurred to obtain issued patents and patent applications pending. The Company expense cost associated with maintaining and defending patents subsequent to their issuance in the period incurred. The Company amortizes patent cost once issued on a straight-line basis over the estimate useful lives of the patents. The Company assess the potential impairment to all capitalized patent cost when events or changes in circumstances indicate that the carrying amount of our patent may not be recoverable. For the years ended December 31, 2012 and 2011 patents costs $18,093 and $0, respectively, are included in the accompanying consolidated balance sheets.

Basic and diluted Net Loss Per Share

Basic and diluted net loss per share has been computed by dividing net loss by the weighted average number of common shares outstanding during the period. All potentially dilutive common shares have been excluded since their inclusion would be anti-dilutive.

In February 2013, the FASB issued Accounting Standards Updated (“ASU”) 2013-04 “Obligations Resulting from Joint and Several Liability Arrangements for Which the Amount at the Reporting Date is Fixed”) ("ASU 2013-04"). The guidance in this update is effective for fiscal years beginning after December 15, 2013 with early adoption permitted. The guidance in this update requires companies to measure obligations resulting from joint and several liability arrangements as the sum of the amount the entity has (a) contractually agreed to pay, and (b) any additional amounts that the entity expects to pay on behalf of its co-obligors. The Company early adopted this guidance in the second quarter of 2013 (Note 12).

Except as noted above, management does not believe that any recently issued, but not yet effective accounting pronouncements, if adopted, would have a significant effect on the accompanying consolidated financial statements.

The Company determined that it was probable that it would not be in a position to comply with these requirements and therefore allocated approximately $360,000 of the proceeds received in this transaction to a registration payment obligation.

Effective May 13, 2013, the Company entered into an employment agreement with Horacio Plotkin, M.D. (the “Plotkin Employment Agreement”) pursuant to which Dr. Plotkin was appointed as Chief Medical Officer of the Company.

In accordance with the terms of the Plotkin Employment Agreement, Dr. Plotkin’s initial base salary is $350,000 and he is eligible to receive a discretionary annual bonus of up to 50% of his then applicable base salary. Additionally, Dr. Plotkin received $20,000 in connection with signing the Plotkin Employment Agreement. Dr. Plotkin will also be awarded options to purchase 120,000 shares of restricted common stock of the Company at an exercise price of $8.70 per share, a pro rata portion of which will vest quarterly during the 3 years following the effective date.

Effective May 20, 2013, the Company entered into an employment agreement with Marc L. Panoff (the “Panoff Employment Agreement”) pursuant to which Mr. Panoff was appointed as Chief Financial Officer and Chief Accounting Officer of the Company.

In accordance with the terms of the Panoff Employment Agreement, Mr. Panoff’s initial base salary is $230,000 and he is eligible to receive a discretionary annual bonus of up to 50% of his then applicable base salary. Mr. Panoff will also be granted 120,000 units of restricted common stock of the Company, a pro rata portion of which will vest quarterly during the 3 years following the effective date.

In the second quarter of 2013, the Company, its Chief Executive Officer and a related party became party to a series of agreements to settle up to $2,286,511 of liabilities, which Company management believes are the primary obligation of the related party. The Company and the related party have entered into indemnification agreements whereby the related party has agreed to defend and hold the Company harmless against all such obligations and amounts, whether paid or unpaid, arising from these agreements. Notwithstanding the indemnification, the Company recorded a $2,286,511 charge to operations during the quarter ended June 30, 2013 that was offset by a corresponding liability of $1,691,400 for the difference between (a) the aggregate amount of all such settlements, and (b) $593,111 of cash and non-cash consideration that the Company paid to immediately settle a portion of the agreement on behalf of the related party. Of the total outstanding $1,691,400 settlement liability, $300,000 is past due, $713,900 was due in July 2013, and $677,500 was due in August 2013. The counter parties to these agreements reserve the right to demand payment at any time. The Chief Executive Officer also agreed to deliver or cause to be delivered 47,128 shares of common stock in the Company to one of the counter parties as a separate component of one of these agreements. Accordingly, the Company does not believe it is required to record a liability for the shared-based component of this specific agreement during the second quarter ended June 30, 2013. There is uncertainty as to whether the related party will have sufficient liquidity to repay the Company or fund the indemnification agreements should it become necessary.

The Company applied the accounting guidance provided in ASU 2013-04. The guidance in this update is effective for fiscal years beginning after December 15, 2013 with early adoption permitted. The guidance in this update requires companies to measure obligations resulting from joint and several liability arrangements as the sum of the amount that the entity has (a) contractually agreed to pay, and (b) any additional amounts that the entity expects to pay on behalf of its co-obligors. The Company has recorded the full amount of the settlements as a charge to its operations due to uncertainty as to whether the related party will have sufficient liquidity to repay the Company or fund the indemnification agreements should it become necessary. Any amounts that the Company may recover under the note due from the related party or under the terms of the indemnification agreement, if in fact any amounts are recovered at all, would be characterized as a capital contribution at the date such payments are received.

In accordance with ASC 855-10, Company management reviewed all material events through the date of this report and there are no material subsequent events to report, other than those listed in the Note.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2012
Summary Of Significant Accounting Policies Policies
Principles of Consolidation	Principles of Consolidation The consolidated financial statements represent the consolidation of the accounts of the Company and its subsidiary in conformity with U.S. GAAP. All intercompany accounts and transactions have been eliminated in consolidation.
Restatement of Previously Issued Financial Statements for Additional Disclosures	The Company, while undergoing a review of its condensed consolidated financial statements for the three and six months periods ended June 30, 2013, commenced an evaluation of its accounting for a series of settlement agreements that the Company, along with certain of its related parties, entered into between April 2013 and June 2013. These agreements, which Company management originally deemed to be the primary obligation of a related party, are more fully described in Notes 2 and 12. On September 13, 2013, Company management, under the authority of the board of directors, determined that these agreements should have been disclosed in the footnotes to its consolidated financial statements for the year ended December 31, 2012. Accordingly, the Company has restated the consolidated financial statements to include these disclosures. The Company also determined that its obligation to pay liquidated damages under a registration payment that it entered into in connection with a financing transaction it completed on February 14, 2013, which required the Company to cause a registration statement to be declared effective by the Securities and Exchange Commission by May 15, 2013, should have also been disclosed. Accordingly, the Company is restating these condensed consolidated financial statements to disclose that it allocated approximately $360,000 of the proceeds received in this financing transaction to a registration payment obligation that was deemed probable at the date that the financing transaction was completed.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the statement of cash flows, the Company considers cash instruments with maturities of less than three months when purchased to be cash equivalents. There are no cash equivalents as of the balance sheet date.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is provided for using the straight-line method over the estimated useful lives of the assets. At December 31, 2012 and 2011, property and equipment consisted of computers with an estimated useful life of three years and leasehold improvements with an estimated life of four years.
Employee Stock-Based Compensation	Employee Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718 Compensation — Stock Compensation (“ASC 718”). ASC 718 addresses all forms of share-based payment (“SBP”) awards including shares issued under employee stock purchase plans and stock incentive shares. Under ASC 718 awards result in a cost that is measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest and will result in a charge to operations.
Non-Employee Stock-Based Compensation	Non-Employee Stock-Based Compensation The Company accounts for equity instruments issued to non-employees in accordance with the provisions of ASC 505, Share Based Payments to Non-Employees, and ASC 718 which requires that such equity instruments are recorded at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. Non-employee stock-based compensation charges are being amortized over their respective contractual vesting periods.
Income Taxes	Income Taxes The Company accounts for income taxes under ASC 740 Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s unaudited financial statements. Since the Company was incorporated on March 11, 2011, all of its years of operations will be subject to examination. The Company believes that its income tax positions and deductions would be sustained on audit and does not anticipate any adjustments that would result in a material changes to its consolidated financial position. The Company’s policy for recording interest and penalties associated with audits is to record such expense as a component of income tax expense. There were no amounts accrued for penalties or interest as of or during the period from March 11, 2011 (inception) through December 31, 2012. Management is currently unaware of any issues under review that could result in significant payments, accruals or material deviations from its position. Prior to conversion into a corporation on September 20, 2012, as a limited liability company, the Company was treated as a partnership for Federal and state income tax purposes. Accordingly, no provision has been made for Federal and state income taxes in the accompanying financial statements for any periods preceding September 20, 2012, since all items of income or loss are required to be reported on the income tax returns of the members, who are responsible for any taxes thereon. Profits and losses are allocated based upon capital in accordance with the permissible methods under Internal Revenue Code Section 706. Further, the Company incurred losses since inception through September 20, 2012, that would have resulted in the recognition of deferred tax assets that would have been fully reserved had the Company been subject to income taxes. The Company is subject to the New York City Unincorporated Business Tax through September 19, 2012. Subsequent to Company’s conversion to a corporation from a limited liability company on September 20, 2012, the Company will report and pay taxes based on its income or loss.
Use of Estimates	Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management is required 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, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. These estimates and assumptions include valuing equity securities in share-based payments, estimating the useful lives of depreciable and amortizable assets and estimating the fair value of long-lived assets to assets whether impairment charges may apply.
Foreign Currency Translation and Remeasurement	Foreign Currency Translation and Remeasurement Under ASC 830 Foreign Currency Matters, functional currency assets and liabilities are translated into the reporting currency, US Dollars, using period end rates of exchange and the related translation adjustments are recorded as a separate component of accumulated other comprehensive income. Functional statements of operations amounts expressed in functional currencies are translated using average exchange rates for the respective periods. Remeasurement adjustments and gains or losses resulting from foreign currency transactions are recorded as foreign exchange gains or losses in the consolidated statements of operations.
Research and Development Costs	Research and Development Costs: Research and development costs are charged to operations as incurred and consist primarily of consulting services. For the year ended December 31, 2012, for the period from March 11, 2011 (inception) through December 31, 2011 and for the period from March 11, 2011 (inception) through December 31, 2012, the Company incurred approximately $524,000, $353,000, and $877,000, respectively, relating to research and development costs that are included in professional fees in the accompanying consolidated statements of operations.
Patents	Patents The Company capitalized external cost, such as filing fees and associated attorney fees, incurred to obtain issued patents and patent applications pending. The Company expense cost associated with maintaining and defending patents subsequent to their issuance in the period incurred. The Company amortizes patent cost once issued on a straight-line basis over the estimate useful lives of the patents. The Company assess the potential impairment to all capitalized patent cost when events or changes in circumstances indicate that the carrying amount of our patent may not be recoverable. For the years ended December 31, 2012 and 2011 patents costs $18,093 and $0, respectively, are included in the accompanying consolidated balance sheets.
Basic and diluted Net Loss Per Share	Basic and diluted Net Loss Per Share Basic and diluted net loss per share has been computed by dividing net loss by the weighted average number of common shares outstanding during the period. All potentially dilutive common shares have been excluded since their inclusion would be anti-dilutive. An aggregate of 267,768 and 1,602,390 common stock equivalents (incentive shares) were excluded from the computation of diluted net loss per common share for the year ended December 31, 2012 and for the period from March 11, 2011 (inception) through December 31, 2011, because they were contingent shares subject to recall.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Management does not believe that any recently issued, but not yet effective accounting pronouncements, if adopted, would have a significant effect on the accompanying consolidated financial statements.
