The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided under such contracts. The Company&#x2019;s objective is to reflect the appropriate trial expenses in its financial statements by matching those expenses with the period in which services are performed and efforts are expended. The Company accounts for these expenses according to the progress of the trial as measured by subject progression and the timing of various aspects of the trial. The Company determines accrual estimates through financial models taking into account discussion with applicable personnel and outside service providers as to the progress or state of consummation of trials, or the services completed. During the course of a clinical trial, the Company adjusts its clinical expense recognition if actual results differ from its estimates. The Company makes estimates of its accrued expenses as of each balance sheet date based on the facts and circumstances known to it at that time. The Company&#x2019;s clinical trial accruals are dependent upon the timely and accurate reporting of contract research organizations and other third-party vendors. Although the Company does not expect its estimates to be materially different from amounts actually incurred, its understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in it reporting amounts that are too high or too low for any particular period.

(&#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 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. (the &#x201C;Company&#x201D;). 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 stockholders of ITI owned 100% of the shares of the Company&#x2019;s outstanding capital stock.</p> <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"> In accordance with Financial Accounting Standards Board (&#x201C;FASB&#x201D;), Accounting Standards Codification (&#x201C;ASC&#x201D;) Topic 805,&#xA0;<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 represented all of the senior management of the combined entity.

Management classifies the Company&#x2019;s investments as available-for-sale. Such securities are carried at estimated fair value, with any unrealized holding gains or losses reported, net of any tax effects reported, as accumulated other comprehensive income, which is a separate component of stockholders&#x2019; equity. Realized gains and losses, and declines in value judged to be other-than-temporary, if any, are included in consolidated results of operations. A decline in the market value of any available-for-sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value, which is charged to earnings in that period, and a new cost basis for the security is established. Dividend and interest income is recognized as interest income when earned. The cost of securities sold is calculated using the specific identification method.</p> <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman';

As of December&#xA0;31, 2015, the Company had $174.8 million of federal net operating loss carryforwards, which expire at various dates through 2035. 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. For the year ended December&#xA0;31, 2015, the Company performed a Section&#xA0;382 ownership analysis and determined that an ownership change occurred (within the meaning of Section&#xA0;382 of the Code) in 2015. Based on the analysis performed, however, the Company does not believe that the Section&#xA0;382 annual limitation will impact the Company&#x2019;s ability to utilize the tax attributes that existed as of the date of the ownership change in a material manner. If the Company experiences an ownership change in the future, the tax benefits related to the NOLs and tax credit carryforwards may be further limited or lost.</p> <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"> At December&#xA0;31, 2015, the Company had $5.7 million in excess tax benefits related to stock-based compensation deductions, the benefit of which will be recorded to additional paid-in-capital once the benefit is realized through a reduction of income taxes payable.

The fair value of share-based payments is estimated, on the date of grant, using the Black-Scholes-Merton option-pricing model (the &#x201C;Black-Scholes model&#x201D;). 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 awards granted with time-based vesting conditions, expense is amortized using the straight-line attribution method. For awards that contain a performance-based vesting condition, expense is amortized using the accelerated attribution method. Share-based compensation expense recognized in the statements of operations for the years ended December&#xA0;31, 2015, 2014 and 2013 is based on share-based awards ultimately expected to vest, and this amount has therefore been reduced for estimated forfeitures. ASC Topic 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 were estimated based on the Company&#x2019;s historical experience 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. Restricted stock units are valued at the fair market value on the date of grant as determined by the closing stock price.</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 limited historical information about the Company&#x2019;s common stock. The expected life of stock options is the period of time for which the stock options are expected to be outstanding. Given the limited historical 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: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"> &#xA0;</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"> Prior to January&#xA0;1, 2014, given that there was no active market for the Company&#x2019;s common stock, 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 August 2013, the Company assumed in the Merger the ITI 2003 Equity Incentive Plan, as amended (the &#x201C;2003 Plan&#x201D;), which expired by its terms in July 2013. As of December&#xA0;31, 2015, there were options to purchase 2,737,657 shares of common stock outstanding under the 2013 Plan. Effective in November 2013, the Company adopted the 2013 Plan. The Company initially reserved 2,850,000 shares of common stock for issuance under the 2013 Plan. In both January 2015 and 2014, the number of shares of common stock reserved for issuance under the 2013 Plan automatically increased by 800,000 pursuant to the evergreen provisions of the 2013 Plan. On June&#xA0;16, 2015, the stockholders of the Company approved, at the Company&#x2019;s 2015 Annual Meeting of Stockholders, an amendment to the 2013 Plan to increase the number of shares of common stock available for issuance under the plan by 3,100,000 shares, to increase by 100,000 shares the maximum number of shares available for the issuance of options, stock appreciation rights and other similar awards to any one participant in any calendar year for purposes of meeting the requirements for qualified performance-based compensation under Section&#xA0;162(m) of the Internal Revenue Code of 1986, as amended (the &#x201C;Code&#x201D;), and to eliminate the evergreen provisions of the 2013 Plan under which 800,000 shares were automatically added to the plan on each of January&#xA0;1, 2014 and 2015.</p> <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"> Stock options granted under the 2013 Plan may be either incentive stock options (&#x201C;ISOs&#x201D;) as defined by the Code, or non-qualified stock options.

Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. To simplify the presentation of deferred income taxes, ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. The amendments in this Update are effective for financial statements issued for annual periods beginning after December&#xA0;15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The Company has elected to adopt this update as of the fourth quarter of 2015, retrospectively. The adoption of this standard did not have a material impact on the Company&#x2019;s consolidated financial statements and accompanying notes.</p> <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"> In May 2014, the FASB issued Accounting Standards Update No.&#xA0;2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 will eliminate transaction-specific and industry-specific revenue recognition guidance under current GAAP and replace it with a principle-based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require 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. In July&#xA0;2015, the FASB decided to defer the effective date of the standard from January&#xA0;1, 2017, to January&#xA0;1, 2018, with an option that permits companies to adopt the standard as early as the original effective date. Early application prior to the original effective date is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method.

Such securities are carried at estimated fair value, with any unrealized holding gains or losses reported, net of any tax effects reported, as accumulated other comprehensive income, which is a separate component of stockholders&#x2019; equity. Realized gains and losses, and declines in value judged to be other-than-temporary, if any, are included in consolidated results of operations. A decline in the market value of any available-for-sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value, which is charged to earnings in that period, and a new cost basis for the security is established. Dividend and interest income is recognized as interest income when earned.

Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. To simplify the presentation of deferred income taxes, ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. The amendments in this Update are effective for financial statements issued for annual periods beginning after December&#xA0;15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The Company has elected to adopt this update as of the fourth quarter of 2015, retrospectively. The adoption of this standard did not have a material impact on the Company&#x2019;s consolidated financial statements and accompanying notes.</p> <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"> In May 2014, the FASB issued Accounting Standards Update No.&#xA0;2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 will eliminate transaction-specific and industry-specific revenue recognition guidance under current GAAP and replace it with a principle-based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require 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. In July&#xA0;2015, the FASB decided to defer the effective date of the standard from January&#xA0;1, 2017, to January&#xA0;1, 2018, with an option that permits companies to adopt the standard as early as the original effective date. Early application prior to the original effective date is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. Presently, the Company is assessing what effect the adoption of this standard will have on our consolidated financial statements and accompanying notes.</p> </div> ITCI 36069237 <div> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> The following table describes the weighted-average assumptions used for calculating the value of options granted during the years ended December&#xA0;31, 2015, 2014 and 2013:</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 12pt; MARGIN-TOP: 0pt"> &#xA0;</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"> </p> <table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="84%" align="center" border="0"> <tr> <td width="79%"></td> <td valign="bottom" width="5%"></td> <td></td> <td></td> <td></td> <td valign="bottom" width="4%"></td> <td></td> <td></td> <td></td> <td valign="bottom" width="4%"></td> <td></td> <td></td> <td></td> </tr> <tr style="FONT-SIZE: 8pt; FONT-FAMILY: Times New Roman"> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;&#xA0;</td> <td style="BORDER-BOTTOM: rgb(0,0,0) 1pt solid" valign="bottom" colspan="2" align="center"><b>2015</b></td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td style="BORDER-BOTTOM: rgb(0,0,0) 1pt solid" valign="bottom" colspan="2" align="center"><b>2014</b></td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td style="BORDER-BOTTOM: rgb(0,0,0) 1pt solid" valign="bottom" colspan="2" align="center"><b>2013</b></td> <td valign="bottom">&#xA0;</td> </tr> <tr style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman" bgcolor="#CCEEFF"> <td valign="top"> <p style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 1em; TEXT-INDENT: -1em"> Dividend yield</p> </td> <td valign="bottom">&#xA0;&#xA0;</td> <td valign="bottom"><b>&#xA0;</b></td> <td valign="bottom" align="right"><b>0</b></td> <td valign="bottom" nowrap="nowrap"><b>%&#xA0;</b></td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">0</td> <td valign="bottom" nowrap="nowrap">%&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">0</td> <td valign="bottom" nowrap="nowrap">%&#xA0;</td> </tr> <tr style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"> <td valign="top"> <p style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 1em; TEXT-INDENT: -1em"> Expected volatility</p> </td> <td valign="bottom">&#xA0;&#xA0;</td> <td valign="bottom"><b>&#xA0;</b></td> <td valign="bottom" align="right"><b>80.0</b></td> <td valign="bottom" nowrap="nowrap"><b>%&#xA0;</b></td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">80.0</td> <td valign="bottom" nowrap="nowrap">%&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">80.0</td> <td valign="bottom" nowrap="nowrap">%&#xA0;</td> </tr> <tr style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman" bgcolor="#CCEEFF"> <td valign="top"> <p style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 1em; TEXT-INDENT: -1em"> Weighted-average risk-free interest rate</p> </td> <td valign="bottom">&#xA0;&#xA0;</td> <td valign="bottom"><b>&#xA0;</b></td> <td valign="bottom" align="right"><b>1.8</b></td> <td valign="bottom" nowrap="nowrap"><b>%&#xA0;</b></td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">2.0</td> <td valign="bottom" nowrap="nowrap">%&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">2.2</td> <td valign="bottom" nowrap="nowrap">%&#xA0;</td> </tr> <tr style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"> <td valign="top"> <p style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 1em; TEXT-INDENT: -1em"> Expected term (in years)</p> </td> <td valign="bottom">&#xA0;&#xA0;</td> <td valign="bottom"><b>&#xA0;</b></td> <td valign="bottom" align="right"><b>5.9</b></td> <td valign="bottom" nowrap="nowrap"><b>&#xA0;&#xA0;</b></td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">6.3</td> <td valign="bottom" nowrap="nowrap">&#xA0;&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom">&#xA0;</td> <td valign="bottom" align="right">6.2</td> <td valign="bottom" nowrap="nowrap">&#xA0;&#xA0;</td> </tr> </table> </div> 0.0000 <div> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"> <b>Income Taxes</b></p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"> Income taxes are accounted for using the liability method.

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.
