The Company reserved 2,850,000 shares of common stock for issuance under the Plan.

ASU 2013-02 provides financial statement issuers the option to disclose significant amounts reclassified from accumulated other comprehensive income separately by each component in either (1)&#xA0;a single note to the financial statements, or (2)&#xA0;parenthetically on the face of the income statement for each line item(s) affected by the reclassification adjustment. The Company adopted the provisions of ASU 2013-02 for the year ended December&#xA0;31, 2013 and elected the first option. However, for the years ended December&#xA0;31, 2013 and 2012, the Company&#x2019;s net loss equaled comprehensive loss, and, therefore, a separate statement of other comprehensive income was not necessary.</p> </div> <div> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"> <b>Share-Based Compensation</b></p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"> Share-based payments are accounted for in accordance with the provisions of ASC&#xA0;718, <i>Compensation&#x2014;Stock Compensation</i> (ASC 718). The fair value of share-based payments is estimated, on the date of grant, using the Black-Scholes-Merton option-pricing model (the Black-Scholes model). The resulting fair value is recognized ratably over the requisite service period, which is generally the vesting period of the option.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> For all time vesting awards granted, expense is amortized using the straight-line attribution method. For awards that contain a performance condition, expense is amortized using the accelerated attribution method. As share-based compensation expense recognized in the statements of operations for the years ended December&#xA0;31, 2013 and 2012, is based on share-based awards ultimately expected to vest, it has been reduced for estimated forfeitures.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures are based on the Company&#x2019;s historical experience for the years ended December&#xA0;31, 2013 and 2012, and have not been material.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> The Company utilizes the Black-Scholes model for estimating fair value of its stock options granted. Option valuation models, including the Black-Scholes model, require the input of subjective assumptions, and changes in the assumptions used can materially affect the grant date fair value of an award. These assumptions include the risk-free rate of interest, expected dividend yield, expected volatility and the expected life of the award.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Expected volatility rates are based on historical volatility of the common stock of comparable publicly traded entities and other factors due to the lack of historic information of the Company&#x2019;s common stock. The expected life of stock-based options is the period of time for which the stock-based options are expected to be outstanding. Given the lack of historic exercise data, the expected life is determined using the &#x201C;simplified method&#x201D; which is defined as the midpoint between the vesting date and the end of the contractual term.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt"> The risk-free interest rates are based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The Company has not paid dividends to its stockholders since its inception and does not plan to pay cash dividends in the foreseeable future. Therefore, the Company has assumed an expected dividend rate of zero.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Given the absence of an active market for the Company&#x2019;s common stock prior to the Merger, the exercise price of the stock options on the date of grant was determined and approved by the board of directors using several factors, including progress and milestones achieved in the Company&#x2019;s business development and performance, the price per share of its convertible preferred stock offerings and general industry and economic trends. In establishing the estimated fair value of the common stock, the Company considered the guidance set forth in American Institute of Certified Public Accountants Practice Guide, <i>Valuation of Privately-Held-Company Equity Securities Issued as Compensation</i>.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Under ASC 718, the cumulative amount of compensation cost recognized for instruments classified as equity that ordinarily would result in a future tax deduction under existing tax law shall be considered to be a deductible difference in applying ASC 740, <i>Income Taxes</i>.

For ITI this determination is generally based on whether the deliverable has &#x201C;stand-alone value&#x201D; to the customer.

This agreement is targeted worldwide, but ITI has retained the option to co-promote with Takeda in the United States.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> Upon execution of the agreement, Takeda made a nonrefundable payment to the Company. ITI is eligible to receive payments of approximately $500&#xA0;million in the aggregate upon achievement of certain development milestones and up to an additional $250&#xA0;million in the aggregate upon achievement of certain sales-based milestones, along with tiered royalty payments based on net sales by Takeda. Takeda will be solely responsible for development, manufacturing and commercialization of PDE1 inhibitors. ITI and Takeda have formed a joint steering committee to coordinate and oversee activities on which the two companies collaborate under the agreement. ITI has the right, but not the obligation, to sit on the joint steering committee. There are no performance, cancellation, termination, or refund provisions in the arrangement that contain material financial consequences to the Company.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> The Company evaluates all deliverables within an arrangement to determine whether or not they provide value on a stand-alone basis.

Based on this evaluation, the deliverables were separated into units of accounting. The arrangement consideration that is fixed or determinable at the inception of the arrangement was allocated to the separate units of accounting based on their relative selling prices. We may exercise significant judgment in determining whether a deliverable is a separate unit of accounting, as well as in estimating the selling prices of such unit of accounting.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> To determine the selling price of a separate deliverable, we use the hierarchy as prescribed in ASC Topic 605-25 based on vendor-specific objective evidence (&#x201C;VSOE&#x201D;), third-party evidence (&#x201C;TPE&#x201D;) or best estimate of selling price (&#x201C;BESP&#x201D;). VSOE is based on the price charged when the element is sold separately and is the price actually charged for that deliverable. TPE is determined based on third-party evidence for a similar deliverable when sold separately and BESP is the price at which we would transact a sale if the elements of collaboration and license arrangements were sold on a stand-alone basis. We were not able to establish VSOE or TPE for the deliverables within collaboration and license arrangements, as we do not have a history of entering into such arrangements or selling the individual deliverables within such arrangements separately. In addition, there may be significant differentiation in these arrangements, which indicates that comparable third-party pricing may not be available. We determined that the selling price for the deliverables within collaboration and license arrangements should be determined using BESP. The process for determining BESP involved significant judgment on our part and included consideration of multiple factors such as prices offered by third parties, estimated direct expenses and other costs, and available data. The Company was able to determine the BESP for the license and R&amp;D services, and thus, allocated the consideration in this arrangement based on relative selling price of each deliverable. The revenue allocated to the license was recognized upon the execution of the agreement as Takeda obtained the right to use the license upon execution of the agreement. The revenue for R&amp;D services is being recognized over the estimated service period of 3 years.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> During the years ended December&#xA0;31, 2013 and December&#xA0;31, 2012, the Company recognized revenue of $2.7&#xA0;million and $3.1&#xA0;million under this agreement, respectively.

As of December&#xA0;31, 2013, the Company had $49.3 million of federal net operating loss carryforwards, which expire at various dates through 2034. The gross amount of the state net operating loss carryforwards is equal to or less than the federal net operating loss carryforwards and expires over various periods based on individual state tax law. In general, businesses with U.S. net operating losses (&#x201C;NOLs&#x201D;) are considered loss corporations for U.S. federal income tax purposes. Pursuant to Section&#xA0;382 of the Code, loss corporations that undergo an ownership change, as defined under the Code, may be subject to an annual limitation on the amount of NOLs (and certain other tax attributes) available to offset taxable income earned after such ownership change. The Company has not performed an analysis to determine if it has triggered any ownership changes pursuant to the rules prescribed under U.S. tax law accordingly the use of the Company&#x2019;s net operating loss carryforwards may be restricted due to changes in Company ownership.</p> <p style="MARGIN-BOTTOM: 0pt;

The Company evaluates the carrying value of those assets in relation to the operating performance of the business and undiscounted cash flows expected to result from the use of those assets.

The Company is reimbursed for certain costs incurred on specified research projects under the terms and conditions of grants, collaboration agreements, and awards. The Company records the amount of reimbursement as revenues on a gross basis in accordance with ASC 605-45, <i>Revenue Recognition/Principal Agent Considerations</i>. The Company is the primary obligor with respect to purchasing goods and services from third-party suppliers, is obligated to compensate the service provider for the work performed, and has discretion in selecting the supplier.

Pursuant to the new standard, each required deliverable is evaluated to determine whether it qualifies as a separate unit of accounting. For ITI this determination is generally based on whether the deliverable has &#x201C;stand-alone value&#x201D; to the customer. The Company adopted this new accounting standard on a prospective basis for all Multiple-Deliverable Revenue Arrangements (MDRAs) entered into on or after January&#xA0;1, 2011, and for any MDRAs that were entered into prior to January&#xA0;1, 2011, but materially modified on or after that date.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> For MDRAs entered into prior to January&#xA0;1, 2011 (pre-2011 arrangements) and not materially modified thereafter, we continue to apply our prior accounting policy with respect to such arrangements. Under this policy, in general, revenue from non-refundable, up-front fees related to intellectual property rights/licenses, where we have continuing involvement and where standalone value could not be determined under the previous guidance, is recognized ratably over the estimated period of ongoing involvement.

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 its respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company accounts for uncertain tax positions pursuant to ASC 740 (previously included in Financial Accounting Standards Board (FASB) Interpretation No.&#xA0;48, <i>Accounting for Uncertainty in Income Taxes&#x2014;an Interpretation of FASB Statement No.&#xA0;109)</i>. Financial statement recognition of a tax position taken or expected to be taken in a tax return is determined based on a more-likely-than-not threshold of that position being sustained. If the tax position meets this threshold, the benefit to be recognized is measured as the tax benefit having the highest likelihood of being realized upon ultimate settlement with the taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"> <b>Comprehensive Income (Loss)</b></p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"> ASC 220-10, <i>Reporting Comprehensive Income</i>, requires the presentation of the comprehensive income or loss and its components as part of the financial statements.

The fair value of share-based payments is estimated, on the date of grant, using the Black-Scholes-Merton option-pricing model (the Black-Scholes model). The resulting fair value is recognized ratably over the requisite service period, which is generally the vesting period of the option.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> For all time vesting awards granted, expense is amortized using the straight-line attribution method. For awards that contain a performance condition, expense is amortized using the accelerated attribution method. As share-based compensation expense recognized in the statements of operations for the years ended December&#xA0;31, 2013 and 2012, is based on share-based awards ultimately expected to vest, it has been reduced for estimated forfeitures.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures are based on the Company&#x2019;s historical experience for the years ended December&#xA0;31, 2013 and 2012, and have not been material.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> The Company utilizes the Black-Scholes model for estimating fair value of its stock options granted. Option valuation models, including the Black-Scholes model, require the input of subjective assumptions, and changes in the assumptions used can materially affect the grant date fair value of an award. These assumptions include the risk-free rate of interest, expected dividend yield, expected volatility and the expected life of the award.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Expected volatility rates are based on historical volatility of the common stock of comparable publicly traded entities and other factors due to the lack of historic information of the Company&#x2019;s common stock. The expected life of stock-based options is the period of time for which the stock-based options are expected to be outstanding. Given the lack of historic exercise data, the expected life is determined using the &#x201C;simplified method&#x201D; which is defined as the midpoint between the vesting date and the end of the contractual term.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt"> The risk-free interest rates are based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The Company has not paid dividends to its stockholders since its inception and does not plan to pay cash dividends in the foreseeable future. Therefore, the Company has assumed an expected dividend rate of zero.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Given the absence of an active market for the Company&#x2019;s common stock prior to the Merger, the exercise price of the stock options on the date of grant was determined and approved by the board of directors using several factors, including progress and milestones achieved in the Company&#x2019;s business development and performance, the price per share of its convertible preferred stock offerings and general industry and economic trends. In establishing the estimated fair value of the common stock, the Company considered the guidance set forth in American Institute of Certified Public Accountants Practice Guide, <i>Valuation of Privately-Held-Company Equity Securities Issued as Compensation</i>.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Under ASC 718, the cumulative amount of compensation cost recognized for instruments classified as equity that ordinarily would result in a future tax deduction under existing tax law shall be considered to be a deductible difference in applying ASC 740, <i>Income Taxes</i>. The deductible temporary difference is based on the compensation cost recognized for financial reporting purposes; however, these provisions currently do not impact the Company, as all the deferred tax assets have a full valuation allowance.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Since the Company had net operating loss carryforwards as of December&#xA0;31, 2013 and 2012, no excess tax benefits for the tax deductions related to share-based awards were recognized in the statements of operations.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> Equity instruments issued to non-employees are accounted for under the provisions of ASC&#xA0;718 and <font style="WHITE-SPACE: nowrap">ASC&#xA0;505-50,</font> <i>Equity/Equity-Based Payments to Non-Employees</i>.

(the &#x201C;Company&#x201D;), through its wholly-owned operating subsidiary, ITI, Inc. (ITI), is a biopharmaceutical company focused on the discovery and clinical development of innovative, small molecule drugs that address underserved medical needs in neuropsychiatric and neurological disorders by targeting intracellular signaling mechanisms within the central nervous system (&#x201C;CNS&#x201D;). The Company&#x2019;s lead product candidate, ITI-007, is in Phase 2 clinical trials as a first-in-class treatment for schizophrenia.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> ITI was incorporated in the State of Delaware on May&#xA0;22, 2001 under the name &#x201C;Intra-Cellular Therapies, Inc.&#x201D; and commenced operations in June&#xA0;2002. ITI was founded to discover and develop drugs for the treatment of neurological and psychiatric disorders.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> On August&#xA0;29, 2013, ITI completed a reverse merger (the &#x201C;Merger&#x201D;) with a public shell company named Oneida Resources Corp. (&#x201C;Oneida&#x201D;). Oneida was formed in August 2012 as a vehicle to investigate and, if such investigation warranted, acquire a target company or business seeking the perceived advantages of being a publicly held corporation. In the Merger, each outstanding share of capital stock of ITI was exchanged for 0.5&#xA0;shares of common stock of Oneida, and each outstanding option to purchase one share of ITI common stock and each outstanding warrant to purchase one share of ITI common stock was assumed by Oneida and became exercisable for 0.5 shares of Oneida common stock. As a result of the Merger and related transactions, ITI survived as a wholly-owned subsidiary of Oneida, Oneida changed its fiscal year end from March&#xA0;31 to December&#xA0;31, and Oneida changed its name to Intra-Cellular Therapies, Inc.. In addition, the Company began operating ITI and its business, and therefore ceased being a shell company. Following the Merger and the redemption of all then outstanding shares of Oneida at the closing of the Merger, the former shareholders of ITI owned 100% of the shares of the Company&#x2019;s outstanding capital stock.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> Immediately prior to the Merger, on August&#xA0;29, 2013, ITI sold to accredited investors approximately $60.0&#xA0;million of its shares of common stock, or 18,889,307 shares at a price of $3.1764 per share (the &#x201C;Private Placement&#x201D;), which included $15.3 million in principal and $0.8 million in accrued interest from the conversion of ITI&#x2019;s then outstanding convertible promissory notes (the &#x201C;Notes&#x201D;).</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> In accordance with Financial Accounting Standards Board (&#x201C;FASB&#x201D;), Accounting Standards Codification (&#x201C;ASC&#x201D;) Topic 805, <i>Business Combinations</i>, ITI is considered the acquirer for accounting purposes, and has accounted for the transaction as a capital transaction, because ITI&#x2019;s former stockholders received 100% of the voting rights in the combined entity and ITI&#x2019;s senior management represents all of the senior management of the combined entity. Consequently, the assets and liabilities and the historical operations that are reflected in the Company&#x2019;s consolidated financial statements are those of ITI and have been recorded at the historical cost basis of the Company. All share and per share amounts in the consolidated financial statements and related notes have been retrospectively adjusted to reflect the one for 0.5 shares common stock exchange as well as the conversion of the Notes and ITI&#x2019;s Series A, B, and C redeemable convertible preferred stock of ITI.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> The Company earns license and collaboration revenue from its significant partnership with Takeda Pharmaceutical Company Limited (&#x201C;Takeda&#x201D;).

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 its respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"> The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company accounts for uncertain tax positions pursuant to ASC 740 (previously included in Financial Accounting Standards Board (FASB) Interpretation No.&#xA0;48, <i>Accounting for Uncertainty in Income Taxes&#x2014;an Interpretation of FASB Statement No.&#xA0;109)</i>. Financial statement recognition of a tax position taken or expected to be taken in a tax return is determined based on a more-likely-than-not threshold of that position being sustained. If the tax position meets this threshold, the benefit to be recognized is measured as the tax benefit having the highest likelihood of being realized upon ultimate settlement with the taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes.</p> </div> 1709255 2737002 574341 6649 278000 332938 31437 29617 0
